Humira treatment should be initiated and supervised by specialist physicians experienced in the diagnosisand treatment of conditions for which Humira is indicated. Ophthalmologists are advised to consult withan appropriate specialist before initiation of treatment with Humira (see section 4.4). Patients treated with
Humira should be given the Patient Reminder Card.
After proper training in injection technique, patients may self-inject with Humira if their physiciandetermines that it is appropriate and with medical follow-up as necessary.
During treatment with Humira, other concomitant therapies (e.g., corticosteroids and/orimmunomodulatory agents) should be optimised.
PosologyRheumatoid arthritisThe recommended dose of Humira for adult patients with rheumatoid arthritis is 40 mg adalimumabadministered every other week as a single dose via subcutaneous injection. Methotrexate should becontinued during treatment with Humira.
Glucocorticoids, salicylates, non-steroidal anti-inflammatory drugs, or analgesics can be continued duringtreatment with Humira. Regarding combination with disease modifying anti-rheumatic drugs other thanmethotrexate see sections 4.4 and 5.1.
In monotherapy, some patients who experience a decrease in their response to Humira 40 mg every otherweek may benefit from an increase in dosage to 40 mg adalimumab every week or 80 mg every otherweek.
Available data suggest that the clinical response is usually achieved within 12 weeks of treatment.
Continued therapy should be reconsidered in a patient not responding within this time period.
Humira may be available in other strengths and/or presentations depending on the individual treatmentneeds.
Dose interruptionThere may be a need for dose interruption, for instance before surgery or if a serious infection occurs.
Available data suggest that re-introduction of Humira after discontinuation for 70 days or longer resultedin the same magnitudes of clinical response and similar safety profile as before dose interruption.
Ankylosing spondylitis, axial spondyloarthritis without radiographic evidence of AS and psoriatic arthritisThe recommended dose of Humira for patients with ankylosing spondylitis, axial spondyloarthritis withoutradiographic evidence of AS and for patients with psoriatic arthritis is 40 mg adalimumab administeredevery other week as a single dose via subcutaneous injection.
Available data suggest that the clinical response is usually achieved within 12 weeks of treatment.
Continued therapy should be reconsidered in a patient not responding within this time period.
PsoriasisThe recommended dose of Humira for adult patients is an initial dose of 80 mg administeredsubcutaneously, followed by 40 mg subcutaneously given every other week starting one week after theinitial dose.
Continued therapy beyond 16 weeks should be carefully reconsidered in a patient not responding withinthis time period.
Beyond 16 weeks, patients with inadequate response to Humira 40 mg every other week may benefit froman increase in dosage to 40 mg every week or 80 mg every other week. The benefits and risks of continued40 mg weekly or 80 mg every other week therapy should be carefully reconsidered in a patient with aninadequate response after the increase in dosage (see section 5.1). If adequate response is achieved with40 mg every week or 80 mg every other week, the dosage may subsequently be reduced to 40 mg everyother week.
Humira may be available in other strengths and/or presentations depending on the individual treatmentneeds.
Hidradenitis suppurativaThe recommended Humira dose regimen for adult patients with hidradenitis suppurativa (HS) is 160 mginitially at Day 1 (given as four 40 mg injections in one day or as two 40 mg injections per day for twoconsecutive days), followed by 80 mg two weeks later at Day 15 (given as two 40 mg injections in oneday). Two weeks later (Day 29) continue with a dose of 40 mg every week or 80 mg every other week(given as two 40 mg injections in one day). Antibiotics may be continued during treatment with Humira ifnecessary. It is recommended that the patient should use a topical antiseptic wash on their HS lesions on adaily basis during treatment with Humira.
Continued therapy beyond 12 weeks should be carefully reconsidered in a patient with no improvementwithin this time period.
Should treatment be interrupted, Humira 40 mg every week or 80 mg every other week may be re-introduced (see section 5.1).
The benefit and risk of continued long-term treatment should be periodically evaluated (see section 5.1).
Humira may be available in other strengths and/or presentations depending on the individual treatmentneeds.
Crohn’s diseaseThe recommended Humira induction dose regimen for adult patients with moderately to severely active
Crohn’s disease is 80 mg at Week 0 followed by 40 mg at Week 2. In case there is a need for a more rapidresponse to therapy, the regimen 160 mg at Week 0 (given as four 40 mg injections in one day or as two40 mg injections per day for two consecutive days), followed by 80 mg at Week 2 (given as two 40 mginjections in one day), can be used with the awareness that the risk for adverse events is higher duringinduction.
After induction treatment, the recommended dose is 40 mg every other week via subcutaneous injection.
Alternatively, if a patient has stopped Humira and signs and symptoms of disease recur, Humira may bere-administered. There is little experience from re-administration after more than 8 weeks since theprevious dose.
During maintenance treatment, corticosteroids may be tapered in accordance with clinical practiceguidelines.
Some patients who experience decrease in their response to Humira 40 mg every other week may benefitfrom an increase in dosage to 40 mg Humira every week or 80 mg every other week.
Some patients who have not responded by Week 4 may benefit from continued maintenance therapythrough Week 12. Continued therapy should be carefully reconsidered in a patient not responding withinthis time period.
Humira may be available in other strengths and/or presentations depending on the individual treatmentneeds.
Ulcerative colitisThe recommended Humira induction dose regimen for adult patients with moderate to severe ulcerativecolitis is 160 mg at Week 0 (given as four 40 mg injections in one day or as two 40 mg injections per dayfor two consecutive days) and 80 mg at Week 2 (given as two 40 mg injections in one day). Afterinduction treatment, the recommended dose is 40 mg every other week via subcutaneous injection.
During maintenance treatment, corticosteroids may be tapered in accordance with clinical practiceguidelines.
Some patients who experience decrease in their response to Humira 40 mg every other week may benefitfrom an increase in dosage to 40 mg Humira every week or 80 mg every other week.
Available data suggest that clinical response is usually achieved within 2-8 weeks of treatment. Humiratherapy should not be continued in patients failing to respond within this time period.
Humira may be available in other strengths and/or presentations depending on the individual treatmentneeds.
UveitisThe recommended dose of Humira for adult patients with uveitis is an initial dose of 80 mg, followed by40 mg given every other week starting one week after the initial dose. There is limited experience in theinitiation of treatment with Humira alone. Treatment with Humira can be initiated in combination withcorticosteroids and/or with other non-biologic immunomodulatory agents. Concomitant corticosteroidsmay be tapered in accordance with clinical practice starting two weeks after initiating treatment with
Humira.
It is recommended that the benefit and risk of continued long-term treatment should be evaluated on ayearly basis (see section 5.1).
Humira may be available in other strengths and/or presentations depending on the individual treatmentneeds.

Summary of the safety profileHumira was studied in 9,506 patients in pivotal controlled and open label trials for up to 60 months ormore. These trials included rheumatoid arthritis patients with short term and long standing disease,juvenile idiopathic arthritis (polyarticular juvenile idiopathic arthritis and enthesitis-related arthritis) aswell as axial spondyloarthritis (ankylosing spondylitis and axial spondyloarthritis without radiographicevidence of AS), psoriatic arthritis, Crohn’s disease, ulcerative colitis, psoriasis, hidradenitis suppurativaand uveitis patients. The pivotal controlled studies involved 6,089 patients receiving Humira and3,801 patients receiving placebo or active comparator during the controlled period.
The proportion of patients who discontinued treatment due to adverse events during the double-blind,controlled portion of pivotal studies was 5.9% for patients taking Humira and 5.4% for control treatedpatients.
The most commonly reported adverse reactions are infections (such as nasopharyngitis, upper respiratorytract infection and sinusitis), injection site reactions (erythema, itching, haemorrhage, pain or swelling),headache and musculoskeletal pain.
Serious adverse reactions have been reported for Humira. TNF-antagonists, such as Humira affect theimmune system and their use may affect the body’s defence against infection and cancer.
Fatal and life-threatening infections (including sepsis, opportunistic infections and TB), HBV reactivationand various malignancies (including leukaemia, lymphoma and HSTCL) have also been reported with useof Humira.
Serious haematological, neurological and autoimmune reactions have also been reported. These includerare reports of pancytopenia, aplastic anaemia, central and peripheral demyelinating events and reports oflupus, lupus-related conditions and Stevens-Johnson syndrome.
Paediatric populationIn general, the adverse events in paediatric patients were similar in frequency and type to those seen inadult patients.
Tabulated list of adverse reactionsThe following list of adverse reactions is based on experience from clinical trials and on postmarketingexperience and are displayed by system organ class and frequency in Table 7 below: very common( 1/10); common ( 1/100 to < 1/10); uncommon ( 1/1,000 to < 1/100); rare ( 1/10,000 to < 1/1,000);and not known (cannot be estimated from the available data). Within each frequency grouping,undesirable effects are presented in order of decreasing seriousness. The highest frequency seen among thevarious indications has been included.

** including open label extension studies1) including spontaneous reporting data2) The mean weight change from baseline for adalimumab ranged from 0.3 kg to 1.0 kg across adultindications compared to (minus) -0.4 kg to 0.4 kg for placebo over a treatment period of 4-6 months.
Weight increase of 5-6 kg has also been observed in long-term extension studies with mean exposures ofapproximately 1-2 years without control group, particularly in patients with Crohn’s disease and
Ulcerative colitis. The mechanism behind this effect is unclear but could be associated with theanti-inflammatory effect of adalimumab.
Hidradenitis suppurativaThe safety profile for patients with HS treated with Humira weekly was consistent with the known safetyprofile of Humira.
UveitisThe safety profile for patients with uveitis treated with Humira every other week was consistent with theknown safety profile of Humira.
Description of selected adverse reactionsInjection site reactionsIn the pivotal controlled trials in adults and children, 12.9% of patients treated with Humira developedinjection site reactions (erythema and/or itching, haemorrhage, pain or swelling), compared to 7.2% ofpatients receiving placebo or active control. Injection site reactions generally did not necessitatediscontinuation of the medicinal product.
InfectionsIn the pivotal controlled trials in adults and children, the rate of infection was 1.51 per patient year in the
Humira treated patients and 1.46 per patient year in the placebo and active control-treated patients. Theinfections consisted primarily of nasopharyngitis, upper respiratory tract infection, and sinusitis. Mostpatients continued on Humira after the infection resolved.
The incidence of serious infections was 0.04 per patient year in Humira treated patients and 0.03 perpatient year in placebo and active control − treated patients.
In controlled and open label adult and paediatric studies with Humira, serious infections (including fatalinfections, which occurred rarely) have been reported, which include reports of tuberculosis (includingmiliary and extra-pulmonary locations) and invasive opportunistic infections (e.g. disseminated orextrapulmonary histoplasmosis, blastomycosis, coccidioidomycosis, pneumocystis, candidiasis,aspergillosis and listeriosis). Most of the cases of tuberculosis occurred within the first eight months afterinitiation of therapy and may reflect recrudescence of latent disease.
Malignancies and lymphoproliferative disordersNo malignancies were observed in 249 paediatric patients with an exposure of 655.6 patient years during
Humira trials in patients with juvenile idiopathic arthritis (polyarticular juvenile idiopathic arthritis andenthesitis-related arthritis). In addition, no malignancies were observed in 192 paediatric patients with anexposure of 498.1 patient years during Humira trials in paediatric patients with Crohn’s disease. Nomalignancies were observed in 77 paediatric patients with an exposure of 80.0 patient years during a
Humira trial in paediatric patients with chronic plaque psoriasis. No malignancies were observed in 93paediatric patients with an exposure of 65.3 patient years during a Humira trial in paediatric patients withulcerative colitis. No malignancies were observed in 60 paediatric patients with an exposure of 58.4patient years during a Humira trial in paediatric patients with uveitis.
During the controlled portions of pivotal Humira trials in adults of at least 12 weeks in duration in patientswith moderately to severely active rheumatoid arthritis, ankylosing spondylitis, axial spondyloarthritiswithout radiographic evidence of AS, psoriatic arthritis, psoriasis, hidradenitis suppurativa, Crohn’sdisease, ulcerative colitis and uveitis, malignancies, other than lymphoma and non-melanoma skin cancer,were observed at a rate (95% confidence interval) of 6.8 (4.4, 10.5) per 1,000 patient-years among 5,291
Humira treated patients versus a rate of 6.3 (3.4, 11.8) per 1,000 patient-years among 3,444 controlpatients (median duration of treatment was 4.0 months for Humira and 3.8 months for control-treatedpatients). The rate (95% confidence interval) of non-melanoma skin cancers was 8.8 (6.0, 13.0) per 1,000patient-years among Humira-treated patients and 3.2 (1.3, 7.6) per 1,000 patient-years among controlpatients. Of these skin cancers, squamous cell carcinomas occurred at rates (95% confidence interval) of2.7 (1.4, 5.4) per 1,000 patient-years among Humira-treated patients and 0.6 (0.1, 4.5) per 1,000 patient-years among control patients. The rate (95% confidence interval) of lymphomas was 0.7 (0.2, 2.7) per1,000 patient-years among Humira-treated patients and 0.6 (0.1, 4.5) per 1,000 patient-years amongcontrol patients.
When combining controlled portions of these trials and ongoing and completed open label extensionstudies with a median duration of approximately 3.3 years including 6,427 patients and over26,439 patient-years of therapy, the observed rate of malignancies, other than lymphoma and non-melanoma skin cancers is approximately 8.5 per 1,000 patient years. The observed rate of non-melanomaskin cancers is approximately 9.6 per 1,000 patient years, and the observed rate of lymphomas isapproximately 1.3 per 1,000 patient years.
In post-marketing experience from January 2003 to December 2010, predominantly in patients withrheumatoid arthritis, the reported rate of malignancies is approximately 2.7 per 1,000 patient treatmentyears. The reported rates for non-melanoma skin cancers and lymphomas are approximately 0.2 and0.3 per 1,000 patient treatment years, respectively (see section 4.4).
Rare post-marketing cases of hepatosplenic T-cell lymphoma have been reported in patients treated withadalimumab (see section 4.4).
AutoantibodiesPatients had serum samples tested for autoantibodies at multiple time points in rheumatoid arthritis studies
I − V. In these trials, 11.9% of patients treated with Humira and 8.1% of placebo and activecontrol − treated patients that had negative baseline anti-nuclear antibody titres reported positive titres at
Week 24. Two patients out of 3,441 treated with Humira in all rheumatoid arthritis and psoriatic arthritisstudies developed clinical signs suggestive of new-onset lupus-like syndrome. The patients improvedfollowing discontinuation of therapy. No patients developed lupus nephritis or central nervous systemsymptoms.
Hepato-biliary eventsIn controlled Phase 3 trials of Humira in patients with rheumatoid arthritis and psoriatic arthritis with acontrol period duration ranging from 4 to 104 weeks, ALT elevations ≥ 3 x ULN occurred in 3.7% of
Humira-treated patients and 1.6% of control-treated patients.
In controlled Phase 3 trials of Humira in patients with polyarticular juvenile idiopathic arthritis who were4 to 17 years and enthesitis-related arthritis who were 6 to 17 years, ALT elevations ≥ 3 x ULN occurredin 6.1% of Humira-treated patients and 1.3% of control-treated patients. Most ALT elevations occurredwith concomitant methotrexate use. No ALT elevations ≥ 3 x ULN occurred in the Phase 3 trial of Humirain patients with polyarticular juvenile idiopathic arthritis who were 2 to <4 years.
In controlled Phase 3 trials of Humira in patients with Crohn’s disease and ulcerative colitis with a controlperiod ranging from 4 to 52 weeks. ALT elevations ≥ 3 x ULN occurred in 0.9% of Humira-treatedpatients and 0.9% of controlled-treated patients.
In the Phase 3 trial of Humira in patients with paediatric Crohn’s disease which evaluated efficacy andsafety of two body weight adjusted maintenance dose regimens following body weight adjusted inductiontherapy up to 52 weeks of treatment, ALT elevations ≥ 3 x ULN occurred in 2.6% (5/192) of patients ofwhom 4 were receiving concomitant immunosuppressants at baseline.
In controlled Phase 3 trials of Humira in patients with plaque Psoriasis with a control period durationranging from 12 to 24 weeks, ALT elevations ≥ 3 x ULN occurred in 1.8% of Humira-treated patients and1.8% of control-treated patients.
No ALT elevations ≥3 X ULN occurred in the Phase 3 trial of Humira in paediatric patients with plaquepsoriasis.
In controlled trials of Humira (initial doses of 160 mg at Week 0 and 80 mg at Week 2, followed by 40 mgevery week starting at Week 4), in patients with hidradenitis suppurativa with a control period durationranging from 12 to 16 weeks, ALT elevations ≥ 3 x ULN occurred in 0.3% of Humira-treated patients and0.6% of control-treated patients.
In controlled trials of Humira (initial doses of 80 mg at Week 0 followed by 40 mg every other weekstarting at Week 1) in adult patients with uveitis up to 80 weeks with a median exposure of 166.5 days and105.0 days in Humira-treated and control-treated patients, respectively, ALT elevations ≥ 3 x ULNoccurred in 2.4% of Humira-treated patients and 2.4% of control-treated patients.
In the controlled Phase 3 trial of Humira in patients with paediatric ulcerative colitis (N=93) whichevaluated efficacy and safety of a maintenance dose of 0.6 mg/kg (maximum of 40 mg) every other week(N=31) and a maintenance dose of 0.6 mg/kg (maximum of 40 mg) every Week (N=32), following bodyweight adjusted induction dosing of 2.4 mg/kg (maximum of 160 mg) at Week 0 and Week 1, and 1.2mg/kg (maximum of 80 mg) at Week 2 (N=63), or an induction dose of 2.4 mg/kg (maximum of 160 mg)at Week 0, placebo at Week 1, and 1.2 mg/kg (maximum of 80 mg) at Week 2 (N=30), ALT elevations ≥3 X ULN occurred in 1.1% (1/93) of patients.
Across all indications in clinical trials patients with raised ALT were asymptomatic and in most caseselevations were transient and resolved on continued treatment. However, there have also been post-marketing reports of liver failure as well as less severe liver disorders that may precede liver failure, suchas hepatitis including autoimmune hepatitis in patients receiving adalimumab.
Concurrent treatment with azathioprine/6-mercaptopurineIn adult Crohn’s disease studies, higher incidences of malignant and serious infection-related adverseevents were seen with the combination of Humira and azathioprine/6-mercaptopurine compared with
Humira alone.
Reporting of suspected adverse reactionsReporting suspected adverse reactions after authorisation of the medicinal product is important. It allowscontinued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals areasked to report any suspected adverse reactions via the national reporting system listed in Appendix V.
Pharmacotherapeutic group: Immunosuppressants, Tumour Necrosis Factor alpha (TNF-α) inhibitors.
ATC code: L04AB04
Mechanism of actionAdalimumab binds specifically to TNF and neutralises the biological function of TNF by blocking itsinteraction with the p55 and p75 cell surface TNF receptors.
Adalimumab also modulates biological responses that are induced or regulated by TNF, including changesin the levels of adhesion molecules responsible for leukocyte migration (ELAM-1, VCAM-1, and ICAM-1with an IC50 of 0.1-0.2 nM).
Pharmacodynamic effectsAfter treatment with Humira, a rapid decrease in levels of acute phase reactants of inflammation(C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR)) and serum cytokines (IL-6) wasobserved, compared to baseline in patients with rheumatoid arthritis. Serum levels of matrixmetalloproteinases (MMP-1 and MMP-3) that produce tissue remodelling responsible for cartilagedestruction were also decreased after Humira administration. Patients treated with Humira usuallyexperienced improvement in haematological signs of chronic inflammation.
A rapid decrease in CRP levels was also observed in patients with polyarticular juvenile idiopathicarthritis, Crohn’s disease, ulcerative colitis and hidradenitis suppurativa after treatment with Humira. Inpatients with Crohn’s disease, a reduction of the number of cells expressing inflammatory markers in thecolon including a significant reduction of expression of TNFα was seen. Endoscopic studies in intestinalmucosa have shown evidence of mucosal healing in adalimumab treated patients.
Clinical efficacy and safetyRheumatoid arthritisHumira was evaluated in over 3,000 patients in all rheumatoid arthritis clinical trials. The efficacy andsafety of Humira were assessed in five randomised, double-blind and well-controlled studies. Somepatients were treated for up to 120 months duration.
RA study I evaluated 271 patients with moderately to severely active rheumatoid arthritis who were 18years old, had failed therapy with at least one disease-modifying, anti rheumatic drug and had insufficientefficacy with methotrexate at doses of 12.5 to 25 mg (10 mg if methotrexate-intolerant) every week andwhose methotrexate dose remained constant at 10 to 25 mg every week. Doses of 20, 40 or 80 mg of
Humira or placebo were given every other week for 24 weeks.
RA study II evaluated 544 patients with moderately to severely active rheumatoid arthritis who were 18years old and had failed therapy with at least one disease-modifying, anti-rheumatic drugs. Doses of 20 or40 mg of Humira were given by subcutaneous injection every other week with placebo on alternativeweeks or every week for 26 weeks; placebo was given every week for the same duration. No otherdisease-modifying anti-rheumatic drugs were allowed.
RA study III evaluated 619 patients with moderately to severely active rheumatoid arthritis who were 18years old, and who had an ineffective response to methotrexate at doses of 12.5 to 25 mg or have beenintolerant to 10 mg of methotrexate every week. There were three groups in this study. The first receivedplacebo injections every week for 52 weeks. The second received 20 mg of Humira every week for52 weeks. The third group received 40 mg of Humira every other week with placebo injections onalternate weeks. Upon completion of the first 52 weeks, 457 patients enrolled in an open-label extensionphase in which 40 mg of Humira/MTX was administered every other week up to 10 years.
RA study IV primarily assessed safety in 636 patients with moderately to severely active rheumatoidarthritis who were 18 years old. Patients were permitted to be either disease-modifying, anti-rheumaticdrug-naïve or to remain on their pre-existing rheumatologic therapy provided that therapy was stable for aminimum of 28 days. These therapies include methotrexate, leflunomide, hydroxychloroquine,sulfasalazine and/or gold salts. Patients were randomised to 40 mg of Humira or placebo every other weekfor 24 weeks.
RA study V evaluated 799 methotrexate-naïve, adult patients with moderate to severely active earlyrheumatoid arthritis (mean disease duration less than 9 months). This study evaluated the efficacy of
Humira 40 mg every other week/methotrexate combination therapy, Humira 40 mg every other weekmonotherapy and methotrexate monotherapy in reducing the signs and symptoms and rate of progressionof joint damage in rheumatoid arthritis for 104 weeks. Upon completion of the first 104 weeks, 497patients enrolled in an open-label extension phase in which 40 mg of Humira was administered everyother week up to 10 years.
The primary end point in RA studies I, II and III and the secondary endpoint in RA study IV was thepercent of patients who achieved an ACR 20 response at Week 24 or 26. The primary endpoint in RAstudy V was the percent of patients who achieved an ACR 50 response at Week 52. RA studies III and Vhad an additional primary endpoint at 52 weeks of retardation of disease progression (as detected by X-rayresults). RA study III also had a primary endpoint of changes in quality of life.
ACR responseThe percent of Humira-treated patients achieving ACR 20, 50 and 70 responses was consistent across RAstudies I, II and III. The results for the 40 mg every other week dose are summarised in Table 8.

In RA studies I-IV, all individual components of the ACR response criteria (number of tender and swollenjoints, physician and patient assessment of disease activity and pain, disability index (HAQ) scores and
CRP (mg/dl) values) improved at 24 or 26 weeks compared to placebo. In RA study III, theseimprovements were maintained throughout 52 weeks.
In the open-label extension for RA study III, most patients who were ACR responders maintainedresponse when followed for up to 10 years. Of 207 patients who were randomised to Humira 40 mg everyother week, 114 patients continued on Humira 40 mg every other week for 5 years. Among those, 86patients (75.4%) had ACR 20 responses; 72 patients (63.2%) had ACR 50 responses; and 41 patients(36%) had ACR 70 responses. Of 207 patients, 81 patients continued on Humira 40 mg every other weekfor 10 years. Among those, 64 patients (79.0%) had ACR 20 responses; 56 patients (69.1%) had ACR 50responses; and 43 patients (53.1%) had ACR 70 responses.
In RA study IV, the ACR 20 response of patients treated with Humira plus standard of care wasstatistically significantly better than patients treated with placebo plus standard of care (p < 0.001).
In RA studies I-IV, Humira-treated patients achieved statistically significant ACR 20 and 50 responsescompared to placebo as early as one to two weeks after initiation of treatment.
In RA study V with early rheumatoid arthritis patients who were methotrexate naïve, combination therapywith Humira and methotrexate led to faster and significantly greater ACR responses than methotrexatemonotherapy and Humira monotherapy at Week 52 and responses were sustained at Week 104 (see Table9).

In the open-label extension for RA study V, ACR response rates were maintained when followed for up to10 years. Of 542 patients who were randomised to Humira 40 mg every other week, 170 patientscontinued on Humira 40 mg every other week for 10 years. Among those, 154 patients (90.6%) had ACR20 responses; 127 patients (74.7%) had ACR 50 responses; and 102 patients (60.0%) had ACR 70responses.
At Week 52, 42.9% of patients who received Humira/methotrexate combination therapy achieved clinicalremission (DAS28 (CRP) < 2.6) compared to 20.6% of patients receiving methotrexate monotherapy and23.4% of patients receiving Humira monotherapy. Humira/methotrexate combination therapy wasclinically and statistically superior to methotrexate (p < 0.001) and Humira monotherapy (p < 0.001) inachieving a low disease state in patients with recently diagnosed moderate to severe rheumatoid arthritis.
The response for the two monotherapy arms was similar (p = 0.447). Of 342 subjects originallyrandomized to Humira monotherapy or Humira/methotrexate combination therapy who entered the open-label extension study, 171 subjects completed 10 years of Humira treatment. Among those, 109 subjects(63.7%) were reported to be in remission at 10 years.
Radiographic responseIn RA study III, where Humira treated patients had a mean duration of rheumatoid arthritis ofapproximately 11 years, structural joint damage was assessed radiographically and expressed as change inmodified Total Sharp Score (TSS) and its components, the erosion score and joint space narrowing score.
Humira/methotrexate patients demonstrated significantly less radiographic progression than patientsreceiving methotrexate alone at 6 and 12 months (see Table 10).
In the open-label extension of RA Study III, the reduction in rate of progression of structural damage ismaintained for 8 and 10 years in a subset of patients. At 8 years, 81 of 207 patients originally treated with40 mg Humira every other week were evaluated radiographically. Among those, 48 patients showed noprogression of structural damage defined by a change from baseline in the mTSS of 0.5 or less. At10 years, 79 of 207 patients originally treated with 40 mg Humira every other week were evaluatedradiographically. Among those, 40 patients showed no progression of structural damage defined by achange from baseline in the mTSS of 0.5 or less.

Following 52 weeks and 104 weeks of treatment, the percentage of patients without progression (changefrom baseline in modified Total Sharp Score 0.5) was significantly higher with Humira/methotrexatecombination therapy (63.8% and 61.2% respectively) compared to methotrexate monotherapy (37.4% and33.5% respectively, p < 0.001) and Humira monotherapy (50.7%, p < 0.002 and 44.5%, p < 0.001respectively).
In the open-label extension of RA study V, the mean change from baseline at Year 10 in the modified
Total Sharp Score was 10.8, 9.2 and 3.9 in patients originally randomized to methotrexate monotherapy,
Humira monotherapy and Humira/methotrexate combination therapy, respectively. The correspondingproportions of patients with no radiographic progression were 31.3%, 23.7% and 36.7% respectively.
Quality of life and physical functionHealth-related quality of life and physical function were assessed using the disability index of the Health
Assessment Questionnaire (HAQ) in the four original adequate and well-controlled trials, which was apre-specified primary endpoint at Week 52 in RA study III. All doses/schedules of Humira in all fourstudies showed statistically significantly greater improvement in the disability index of the HAQ frombaseline to Month 6 compared to placebo and in RA study III the same was seen at Week 52. Results fromthe Short Form Health Survey (SF 36) for all doses/schedules of Humira in all four studies support thesefindings, with statistically significant physical component summary (PCS) scores, as well as statisticallysignificant pain and vitality domain scores for the 40 mg every other week dose. A statistically significantdecrease in fatigue as measured by functional assessment of chronic illness therapy (FACIT) scores wasseen in all three studies in which it was assessed (RA studies I, III, IV).
In RA study III, most subjects who achieved improvement in physical function and continued treatmentmaintained improvement through Week 520 (120 months) of open-label treatment. Improvement inquality of life was measured up to Week 156 (36 months) and improvement was maintained through thattime.
In RA study V, the improvement in the HAQ disability index and the physical component of the SF 36showed greater improvement (p < 0.001) for Humira/methotrexate combination therapy versusmethotrexate monotherapy and Humira monotherapy at Week 52, which was maintained through
Week 104. Among the 250 subjects who completed the open-label extension study, improvements inphysical function were maintained through 10 years of treatment.
Axial spondyloarthritisAnkylosing spondylitis (AS)Humira 40 mg every other week was assessed in 393 patients in two randomised, 24 week double − blind,placebo − controlled studies in patients with active ankylosing spondylitis (mean baseline score of diseaseactivity [Bath Ankylosing Spondylitis Disease Activity Index (BASDAI)] was 6.3 in all groups) who havehad an inadequate response to conventional therapy. Seventy-nine (20.1%) patients were treatedconcomitantly with disease modifying anti − rheumatic drugs, and 37 (9.4%) patients withglucocorticoids. The blinded period was followed by an open − label period during which patientsreceived Humira 40 mg every other week subcutaneously for up to an additional 28 weeks. Subjects(n=215, 54.7%) who failed to achieve ASAS 20 at Weeks 12, or 16 or 20 received early escape open-labeladalimumab 40 mg every other week subcutaneously and were subsequently treated as non-responders inthe double-blind statistical analyses.
In the larger AS study I with 315 patients, results showed statistically significant improvement of the signsand symptoms of ankylosing spondylitis in patients treated with Humira compared to placebo. Significantresponse was first observed at Week 2 and maintained through 24 weeks (Table 12).

Humira treated patients had significantly greater improvement at Week 12 which was maintained through
Week 24 in both the SF36 and Ankylosing Spondylitis Quality of Life Questionnaire (ASQoL).
Similar trends (not all statistically significant) were seen in the smaller randomised, double − blind,placebo controlled AS study II of 82 adult patients with active ankylosing spondylitis.
Axial spondyloarthritis without radiographic evidence of ASThe safety and efficacy of Humira were assessed in two randomized, double-blind placebo-controlledstudies in patients with non-radiographic axial spondyloarthritis (nr-axSpA). Study nr-axSpA I evaluatedpatients with active nr-axSpA. Study nr-axSpA II was a treatment withdrawal study in active nr-axSpApatients who achieved remission during open-label treatment with Humira.
Study nr-axSpA I
In Study nr-axSpA I, Humira 40 mg every other week was assessed in 185 patients in a randomised,12 week double - blind, placebo - controlled study in patients with active nr-axSpA (mean baseline scoreof disease activity [Bath Ankylosing Spondylitis Disease Activity Index (BASDAI)] was 6.4 for patientstreated with Humira and 6.5 for those on placebo) who have had an inadequate response to or intoleranceto 1 NSAIDs, or a contraindication for NSAIDs.
Thirty-three (18%) patients were treated concomitantly with disease modifying anti-rheumatic drugs, and146 (79%) patients with NSAIDs at baseline. The double-blind period was followed by an open-labelperiod during which patients receive Humira 40 mg every other week subcutaneously for up to anadditional 144 weeks. Week 12 results showed statistically significant improvement of the signs andsymptoms of active nr-axSpA in patients treated with Humira compared to placebo (Table 13).

Inhibition of inflammation
Significant improvement of signs of inflammation as measured by hs-CRP and MRI of both Sacroiliac
Joints and the Spine was maintained in Humira-treated patients through Week 156 and Week 104,respectively.
Quality of life and physical functionHealth-related quality of life and physical function were assessed using the HAQ-S and the SF-36questionnaires. Humira showed statistically significantly greater improvement in the HAQ-S total scoreand the SF-36 Physical Component Score (PCS) from baseline to Week 12 compared to placebo.
Improvement in health-related quality of life and physical function was maintained during the open-labelextension through Week 156.
Study nr-axSpA II673 patients with active nr-axSpA (mean baseline disease activity [BASDAI] was 7.0) who had aninadequate response to 2 NSAIDs, or an intolerance to or a contraindication for NSAIDs enrolled intothe open-label period of Study nr-axSpA II during which they received Humira 40 mg eow for 28 weeks.
These patients also had objective evidence of inflammation in the sacroiliac joints or spine on MRI orelevated hs-CRP. Patients who achieved sustained remission for at least 12 weeks (N=305) (ASDAS < 1.3at Weeks 16, 20, 24, and 28) during the open-label period were then randomized to receive eithercontinued treatment with Humira 40 mg eow (N=152) or placebo (N=153) for an additional 40 weeks in adouble-blind, placebo-controlled period (total study duration 68 weeks). Subjects who flared during thedouble-blind period were allowed Humira 40 mg eow rescue therapy for at least 12 weeks.
The primary efficacy endpoint was the proportion of patients with no flare by Week 68 of the study. Flarewas defined as ASDAS ≥ 2.1 at two consecutive visits four weeks apart. A greater proportion of patientson Humira had no disease flare during the double-blind period, when compared with those on placebo(70.4% vs. 47.1%, p<0.001) (Figure 1).

Psoriatic arthritisHumira, 40 mg every other week, was studied in patients with moderately to severely active psoriaticarthritis in two placebo-controlled studies, PsA studies I and II. PsA study I with 24 week duration,treated 313 adult patients who had an inadequate response to non-steroidal anti-inflammatory drug therapyand of these, approximately 50% were taking methotrexate. PsA study II with 12-week duration, treated100 patients who had an inadequate response to DMARD therapy. Upon completion of both studies, 383patients enrolled in an open-label extension study, in which 40 mg Humira was administered every otherweek.
There is insufficient evidence of the efficacy of Humira in patients with ankylosing spondylitis-likepsoriatic arthropathy due to the small number of patients studied.

ACR responses in PsA study I were similar with and without concomitant methotrexate therapy.
ACR responses were maintained in the open-label extension study for up to 136 weeks.
Radiographic changes were assessed in the psoriatic arthritis studies. Radiographs of hands, wrists, andfeet were obtained at baseline and Week 24 during the double-blind period when patients were on Humiraor placebo and at Week 48 when all patients were on open-label Humira. A modified Total Sharp Score(mTSS), which included distal interphalangeal joints (i.e. not identical to the TSS used for rheumatoidarthritis), was used.
Humira treatment reduced the rate of progression of peripheral joint damage compared with placebotreatment as measured by change from baseline in mTSS (mean ± SD) 0.8 ± 2.5 in the placebo group (at
Week 24) compared with 0.0 ± 1.9; (p< 0.001) in the Humira group (at Week 48).
In subjects treated with Humira with no radiographic progression from baseline to Week 48 (n=102), 84%continued to show no radiographic progression through 144 weeks of treatment.
Humira treated patients demonstrated statistically significant improvement in physical function as assessedby HAQ and Short Form Health Survey (SF 36) compared to placebo at Week 24. Improved physicalfunction continued during the open label extension up to Week 136.
PsoriasisThe safety and efficacy of Humira were studied in adult patients with chronic plaque psoriasis ( 10%
BSA involvement and Psoriasis Area and Severity Index (PASI) 12 or 10) who were candidates forsystemic therapy or phototherapy in randomised, double-blind studies. 73% of patients enrolled in
Psoriasis Studies I and II had received prior systemic therapy or phototherapy. The safety and efficacy of
Humira were also studied in adult patients with moderate to severe chronic plaque psoriasis withconcomitant hand and/or foot psoriasis who were candidates for systemic therapy in a randomised double-blind study (Psoriasis Study III).
Psoriasis Study I (REVEAL) evaluated 1,212 patients within three treatment periods. In period A, patientsreceived placebo or Humira at an initial dose of 80 mg followed by 40 mg every other week starting oneweek after the initial dose. After 16 weeks of therapy, patients who achieved at least a PASI 75 response(PASI score improvement of at least 75% relative to baseline), entered period B and received open-label40 mg Humira every other week. Patients who maintained PASI 75 response at Week 33 and wereoriginally randomised to active therapy in Period A, were re-randomised in period C to receive 40 mg
Humira every other week or placebo for an additional 19 weeks. Across all treatment groups, the meanbaseline PASI score was 18.9 and the baseline Physician’s Global Assessment (PGA) score ranged from“moderate” (53% of subjects included) to “severe” (41%) to “very severe” (6%).
Psoriasis Study II (CHAMPION) compared the efficacy and safety of Humira versus methotrexate andplacebo in 271 patients. Patients received placebo, an initial dose of MTX 7.5 mg and thereafter doseincreases up to Week 12, with a maximum dose of 25 mg or an initial dose of 80 mg Humira followed by40 mg every other week (starting one week after the initial dose) for 16 weeks. There are no data availablecomparing Humira and MTX beyond 16 weeks of therapy. Patients receiving MTX who achieved aPASI 50 response at Week 8 and/or 12 did not receive further dose increases. Across all treatmentgroups, the mean baseline PASI score was 19.7 and the baseline PGA score ranged from “mild” (<1%) to“moderate” (48%) to “severe” (46%) to “very severe” (6%).
Patients participating in all Phase 2 and Phase 3 psoriasis studies were eligible to enrol into an open-labelextension trial, where Humira was given for at least an additional 108 weeks.
In Psoriasis Studies I and II, a primary endpoint was the proportion of patients who achieved a PASI 75response from baseline at Week 16 (see Tables 16 and 17).

In Psoriasis Study I, 28% of patients who were PASI 75 responders and were re-randomised to placebo at
Week 33 compared to 5% continuing on Humira, p<0.001, experienced “loss of adequate response” (PASIscore after Week 33 and on or before Week 52 that resulted in a <PASI 50 response relative to baselinewith a minimum of a 6-point increase in PASI score relative to Week 33). Of the patients who lostadequate response after re-randomisation to placebo who then enrolled into the open-label extension trial,38% (25/66) and 55% (36/66) regained PASI 75 response after 12 and 24 weeks of re-treatment,respectively.
A total of 233 PASI 75 responders at Week 16 and Week 33 received continuous Humira therapy for52 weeks in Psoriasis Study I, and continued Humira in the open-label extension trial. PASI 75 and PGAof clear or minimal response rates in these patients were 74.7% and 59.0%, respectively, after anadditional 108 weeks of open-label therapy (total of 160 weeks). In an analysis in which all patients whodropped out of the study for adverse events or lack of efficacy, or who dose-escalated, were considerednon-responders, PASI 75 and PGA of clear or minimal response rates in these patients were 69.6% and55.7%, respectively, after an additional 108 weeks of open-label therapy (total of 160 weeks).
A total of 347 stable responders participated in a withdrawal and retreatment evaluation in an open-labelextension study. During the withdrawal period, symptoms of psoriasis returned over time with a mediantime to relapse (decline to PGA “moderate” or worse) of approximately 5 months. None of these patientsexperienced rebound during the withdrawal period. A total of 76.5% (218/285) of patients who entered theretreatment period had a response of PGA “clear” or “minimal” after 16 weeks of retreatment, irrespectiveof whether they relapsed during withdrawal (69.1%[123/178] and 88.8% [95/107] for patients whorelapsed and who did not relapse during the withdrawal period, respectively). A similar safety profile wasobserved during retreatment as before withdrawal.
Significant improvements at Week 16 from baseline compared to placebo (Studies I and II) and MTX(Study II) were demonstrated in the DLQI (Dermatology Life Quality Index). In Study I, improvements inthe physical and mental component summary scores of the SF-36 were also significant compared toplacebo.
In an open-label extension study, for patients who dose escalated from 40 mg every other week to 40 mgweekly due to a PASI response below 50%, 26.4% (92/349) and 37.8% (132/349) of patients achieved
PASI 75 response at Week 12 and 24, respectively.
Psoriasis Study III (REACH) compared the efficacy and safety of Humira versus placebo in 72 patientswith moderate to severe chronic plaque psoriasis and hand and/or foot psoriasis. Patients received aninitial dose of 80 mg Humira followed by 40 mg every other week (starting one week after the initial dose)or placebo for 16 weeks. At Week 16, a statistically significantly greater proportion of patients whoreceived Humira achieved PGA of 'clear' or 'almost clear' for the hands and/or feet compared to patientswho received placebo (30.6% versus 4.3%, respectively [P = 0.014]).
Psoriasis Study IV compared efficacy and safety of Humira versus placebo in 217 adult patients withmoderate to severe nail psoriasis. Patients received an initial dose of 80 mg Humira followed by 40 mgevery other week (starting one week after the initial dose) or placebo for 26 weeks followed by open-label
Humira treatment for an additional 26 weeks. Nail psoriasis assessments included the Modified Nail
Psoriasis Severity Index (mNAPSI), the Physician’s Global Assessment of Fingernail Psoriasis (PGA-F)and the Nail Psoriasis Severity Index (NAPSI) (see Table 18). Humira demonstrated a treatment benefit innail psoriasis patients with different extents of skin involvement (BSA≥10% (60% of patients) and
BSA<10% and ≥5% (40% of patients)).

Hidradenitis suppurativaThe safety and efficacy of Humira were assessed in randomised, double-blind, placebo-controlled studiesand an open-label extension study in adult patients with moderate to severe hidradenitis suppurativa (HS)who were intolerant, had a contraindication or an inadequate response to at least a 3-month trial ofsystemic antibiotic therapy. The patients in HS-I and HS-II had Hurley Stage II or III disease with at least3 abscesses or inflammatory nodules.
Study HS-I (PIONEER I) evaluated 307 patients with 2 treatment periods. In Period A, patients receivedplacebo or Humira at an initial dose of 160 mg at Week 0, 80 mg at Week 2, and 40 mg every weekstarting at Week 4 to Week 11. Concomitant antibiotic use was not allowed during the study. After12 weeks of therapy, patients who had received Humira in Period A were re-randomised in Period B to 1of 3 treatment groups (Humira 40 mg every week, Humira 40 mg every other week, or placebo from
Week 12 to Week 35). Patients who had been randomised to placebo in Period A were assigned to receive
Humira 40 mg every week in Period B.
Study HS-II (PIONEER II) evaluated 326 patients with 2 treatment periods. In Period A, patients receivedplacebo or Humira at an initial dose of 160 mg at Week 0 and 80 mg at Week 2 and 40 mg every weekstarting at Week 4 to Week 11. 19.3% of patients had continued baseline oral antibiotic therapy during thestudy. After 12 weeks of therapy, patients who had received Humira in Period A were re-randomised in
Period B to 1 of 3 treatment groups (Humira 40 mg every week, Humira 40 mg every other week, orplacebo from Week 12 to Week 35). Patients who had been randomised to placebo in Period A wereassigned to receive placebo in Period B.
Patients participating in Studies HS-I and HS-II were eligible to enrol into an open-label extension studyin which Humira 40mg was administered every week. Mean exposure in all adalimumab population was762 days. Throughout all 3 studies patients used topical antiseptic wash daily.
Clinical Response
Reduction of inflammatory lesions and prevention of worsening of abscesses and draining fistulas wasassessed using Hidradenitis Suppurativa Clinical Response (HiSCR; at least a 50% reduction in totalabscess and inflammatory nodule count with no increase in abscess count and no increase in drainingfistula count relative to Baseline). Reduction in HS-related skin pain was assessed using a Numeric Rating
Scale in patients who entered the study with an initial baseline score of 3 or greater on a 11 point scale.
At Week 12, a significantly higher proportion of patients treated with Humira versus placebo achieved
HiSCR. At Week 12, a significantly higher proportion of patients in Study HS-II experienced a clinicallyrelevant decrease in HS-related skin pain (see Table 19). Patients treated with Humira had significantlyreduced risk of disease flare during the initial 12 weeks of treatment.

Treatment with Humira 40 mg every week significantly reduced the risk of worsening of abscesses anddraining fistulas. Approximately twice the proportion of patients in the placebo group in the first 12 weeksof Studies HS-I and HS-II, compared with those in the Humira group experienced worsening of abscesses(23.0% vs 11.4%, respectively) and draining fistulas (30.0% vs 13.9%, respectively).
Greater improvements at Week 12 from baseline compared to placebo were demonstrated in skin-specifichealth-related quality of life, as measured by the Dermatology Life Quality Index (DLQI; Studies HS-Iand HS-II), patient global satisfaction with medication treatment as measured by the Treatment
Satisfaction Questionnaire - medication (TSQM; Studies HS-I and HS-II), and physical health asmeasured by the physical component summary score of the SF-36 (Study HS-I).
In patients with at least a partial response to Humira 40 mg weekly at Week 12, the HiSCR rate at
Week 36 was higher in patients who continued weekly Humira than in patients in whom dosing frequencywas reduced to every other week, or in whom treatment was withdrawn (see Table 20).

b Patients meeting protocol-specified criteria for loss of response or noimprovement were required to discontinue from the studies and werecounted as nonresponders.
Among patients who were at least partial responders at Week 12, and who received continuous weekly
Humira therapy, the HiSCR rate at Week 48 was 68.3% and at Week 96 was 65.1%. Longer termtreatment with Humira 40 mg weekly for 96 weeks identified no new safety findings.
Among patients whose Humira treatment was withdrawn at Week 12 in Studies HS-I and HS-II, the
HiSCR rate 12 weeks after re-introduction of Humira 40 mg weekly returned to levels similar to thatobserved before withdrawal (56.0 %).
Crohn’s diseaseThe safety and efficacy of Humira were assessed in over 1500 patients with moderately to severely active
Crohn’s disease (Crohn’s Disease Activity Index (CDAI) 220 and 450) in randomised, double-blind,placebo-controlled studies. Concomitant stable doses of aminosalicylates, corticosteroids, and/orimmunomodulatory agents were permitted and 80% of patients continued to receive at least one of thesemedications.
Induction of clinical remission (defined as CDAI < 150) was evaluated in two studies, CD Study I(CLASSIC I) and CD Study II (GAIN). In CD Study I, 299 TNF-antagonist naive patients wererandomised to one of four treatment groups; placebo at Weeks 0 and 2, 160 mg Humira at Week 0 and80 mg at Week 2, 80 mg at Week 0 and 40 mg at Week 2, and 40 mg at Week 0 and 20 mg at Week 2. In
CD Study II, 325 patients who had lost response or were intolerant to infliximab were randomised toreceive either 160 mg Humira at Week 0 and 80 mg at Week 2 or placebo at Weeks 0 and 2. The primarynon-responders were excluded from the studies and therefore these patients were not further evaluated.
Maintenance of clinical remission was evaluated in CD study III (CHARM). In CD Study III, 854 patientsreceived open-label 80 mg at Week 0 and 40 mg at Week 2. At Week 4 patients were randomised to40 mg every other week, 40 mg every week, or placebo with a total study duration of 56 weeks. Patients inclinical response (decrease in CDAI ≥ 70) at Week 4 were stratified and analysed separately from thosenot in clinical response at Week 4. Corticosteroid taper was permitted after Week 8.
CD study I and CD study II induction of remission and response rates are presented in Table 21.

Similar remission rates were observed for the 160/80 mg and 80/40 mg induction regimens by Week 8 andadverse events were more frequently noted in the 160/80 mg group.
In CD Study III, at Week 4, 58% (499/854) of patients were in clinical response and were assessed in theprimary analysis. Of those in clinical response at Week 4, 48% had been previously exposed to other TNF-antagonists. Maintenance of remission and response rates are presented in Table 22. Clinical remissionresults remained relatively constant irrespective of previous TNF-antagonist exposure.
Disease-related hospitalisations and surgeries were statistically significantly reduced with adalimumabcompared with placebo at Week 56.

Among patients who were not in response at Week 4, 43% of Humira maintenance patients responded by
Week 12 compared to 30% of placebo maintenance patients. These results suggest that some patients whohave not responded by Week 4 benefit from continued maintenance therapy through Week 12. Therapycontinued beyond 12 weeks did not result in significantly more responses (see section 4.2).
117/276 patients from CD study I and 272/777 patients from CD studies II and III were followed throughat least 3 years of open-label adalimumab therapy. 88 and 189 patients, respectively, continued to be inclinical remission. Clinical response (CR-100) was maintained in 102 and 233 patients, respectively.
Quality of lifeIn CD Study I and CD Study II, statistically significant improvement in the disease-specific inflammatorybowel disease questionnaire (IBDQ) total score was achieved at Week 4 in patients randomised to Humira80/40 mg and 160/80 mg compared to placebo and was seen at Weeks 26 and 56 in CD Study III as wellamong the adalimumab treatment groups compared to the placebo group.
Ulcerative colitisThe safety and efficacy of multiple doses of Humira were assessed in adult patients with moderately toseverely active ulcerative colitis (Mayo score 6 to 12 with endoscopy subscore of 2 to 3) in randomised,double-blind, placebo-controlled studies.
In study UC-I, 390 TNF-antagonist naïve patients were randomised to receive either placebo at Weeks 0and 2, 160 mg Humira at Week 0 followed by 80 mg at Week 2, or 80 mg Humira at Week 0 followedby 40 mg at Week 2. After Week 2, patients in both adalimumab arms received 40 mg eow. Clinicalremission (defined as Mayo score ≤ 2 with no subscore > 1) was assessed at Week 8.
In study UC-II, 248 patients received 160 mg of Humira at Week 0, 80 mg at Week 2 and 40 mg eowthereafter, and 246 patients received placebo. Clinical results were assessed for induction of remission at
Week 8 and for maintenance of remission at Week 52.
Patients induced with 160/80 mg Humira achieved clinical remission versus placebo at Week 8 instatistically significantly greater percentages in study UC-I (18% vs. 9% respectively, p=0.031) and study
UC-II (17% vs. 9% respectively, p=0.019). In study UC-II, among those treated with Humira who were inremission at Week 8, 21/41 (51%) were in remission at Week 52.
Results from the overall UC-II study population are shown in Table 23.

Of those patients who had a response at Week 8, 47% were in response, 29% were in remission, 41% hadmucosal healing, and 20% were in steroid-free remission for ≥ 90 days at Week 52.
Approximately 40% of patients in study UC-II had failed prior anti-TNF treatment with infliximab. Theefficacy of adalimumab in those patients was reduced compared to that in anti-TNF naïve patients.
Among patients who had failed prior anti-TNF treatment, Week 52 remission was achieved by 3% onplacebo and 10% on adalimumab.
Patients from studies UC-I and UC-II had the option to roll over into an open-label long-term extensionstudy (UC III). Following 3 years of adalimumab therapy, 75% (301/402) continued to be in clinicalremission per partial Mayo score.
Hospitalisation ratesDuring 52 weeks of studies UC-I and UC-II, lower rates of all-cause hospitalisations and UC-relatedhospitalisations were observed for the adalimumab-treated arm compared to the placebo arm. The numberof all cause hospitalisations in the adalimumab treatment group was 0.18 per patient year vs. 0.26 perpatient year in the placebo group and the corresponding figures for UC-related hospitalisations were 0.12per patient year vs. 0.22 per patient year.
Quality of lifeIn study UC-II, treatment with adalimumab resulted in improvements in the Inflammatory Bowel Disease
Questionnaire (IBDQ) score.
UveitisThe safety and efficacy of Humira were assessed in adult patients with non-infectious intermediate,posterior, and panuveitis, excluding patients with isolated anterior uveitis, in two randomised, double-masked, placebo-controlled studies (UV I and II). Patients received placebo or Humira at an initial dose of80 mg followed by 40 mg every other week starting one week after the initial dose. Concomitant stabledoses of one non-biologic immunosuppressant were permitted.
Study UV I evaluated 217 patients with active uveitis despite treatment with corticosteroids (oralprednisone at a dose of 10 to 60 mg/day). All patients received a 2-week standardised dose of prednisone60 mg/day at study entry followed by a mandatory taper schedule, with complete corticosteroiddiscontinuation by Week 15.
Study UV II evaluated 226 patients with inactive uveitis requiring chronic corticosteroid treatment (oralprednisone 10 to 35 mg/day) at baseline to control their disease. Patients subsequently underwent amandatory taper schedule, with complete corticosteroid discontinuation by Week 19.
The primary efficacy endpoint in both studies was t́ime to treatment failure´. Treatment failure wasdefined by a multi-component outcome based on inflammatory chorioretinal and/or inflammatory retinalvascular lesions, anterior chamber (AC) cell grade, vitreous haze (VH) grade and best corrected visualacuity (BCVA).
Patients who completed Studies UV I and UV II were eligible to enroll in an uncontrolled long-termextension study with an originally planned duration of 78 weeks. Patients were allowed to continue onstudy medication beyond Week 78 until they had access to Humira.
Clinical Response
Results from both studies demonstrated statistically significant reduction of the risk of treatment failure inpatients treated with Humira versus patients receiving placebo (See Table 24). Both studies demonstratedan early and sustained effect of Humira on the treatment failure rate versus placebo (see Figure 2).

In Study UV I statistically significant differences in favour of adalimumab versus placebo were observedfor each component of treatment failure. In Study UV II, statistically significant differences wereobserved for visual acuity only, but the other components were numerically in favour of adalimumab.
Of the 424 subjects included in the uncontrolled long-term extension of Studies UV I and UV II, 60subjects were regarded ineligible (e.g. due to deviations or due to complications secondary to diabeticretinopathy, due to cataract surgery or vitrectomy) and were excluded from the primary analysis ofefficacy. Of the 364 remaining patients, 269 evaluable patients (74%) reached 78 weeks of open-labeladalimumab treatment. Based on the observed data approach, 216 (80.3%) were in quiescence (no activeinflammatory lesions, AC cell grade ≤ 0.5+, VH grade ≤ 0.5+) with a concomitant steroid dose ≤ 7.5 mgper day, and 178 (66.2%) were in steroid-free quiescence. BCVA was either improved or maintained (< 5letters deterioration) in 88.6% of the eyes at week 78. Data beyond Week 78 were generally consistentwith these results but the number of enrolled subjects declined after this time. Overall, among the patientswho discontinued the study, 18% discontinued due to adverse events, and 8% due to insufficient responseto adalimumab treatment.
Quality of Life
Patient reported outcomes regarding vision-related functioning were measured in both clinical studies,using the NEI VFQ-25. Humira was numerically favoured for the majority of subscores with statisticallysignificant mean differences for general vision, ocular pain, near vision, mental health, and total score in
Study UV I, and for general vision and mental health in Study UV II. Vision related effects were notnumerically in favour of Humira for colour vision in Study UVI and for colour vision, peripheral visionand near vision in Study UV II.
ImmunogenicityFormation of anti-adalimumab antibodies is associated with increased clearance and reduced efficacy ofadalimumab. There is no apparent correlation between the presence of anti-adalimumab antibodies and theoccurrence of adverse events.
TREATMENT FAILURE RATE (%)
Patients in rheumatoid arthritis studies I, II and III were tested at multiple time points for anti-adalimumabantibodies during the 6 to 12 month period. In the pivotal trials, anti-adalimumab antibodies wereidentified in 5.5% (58/1053) of patients treated with adalimumab, compared to 0.5% (2/370) on placebo.
In patients not given concomitant methotrexate, the incidence was 12.4%, compared to 0.6% whenadalimumab was used as add-on to methotrexate.
In patients with polyarticular juvenile idiopathic arthritis who were 4 to 17 years, anti-adalimumabantibodies were identified in 15.8% (27/171) of patients treated with adalimumab. In patients not givenconcomitant methotrexate, the incidence was 25.6% (22/86) compared to 5.9% (5/85) when adalimumabwas used as add-on to methotrexate. In patients with polyarticular juvenile idiopathic arthritis who were2 to <4 years old or aged 4 and above weighing <15 kg, anti-adalimumab antibodies were identified in 7%(1/15) of patients, and the one patient was receiving concomitant methotrexate.
In patients with enthesitis-related arthritis, anti-adalimumab antibodies were identified in 10.9% (5/46) ofpatients treated with adalimumab. In patients not given concomitant methotrexate, the incidence was13.6% (3/22), compared to 8.3% (2/24) when adalimumab was used as add-on to methotrexate.
In patients with psoriatic arthritis, anti-adalimumab antibodies were identified in 38/376 subjects (10%)treated with adalimumab. In patients not given concomitant methotrexate, the incidence was 13.5%(24/178 subjects), compared to 7% (14 of 198 subjects) when adalimumab was used as add-on tomethotrexate.
In patients with ankylosing spondylitis anti-adalimumab antibodies were identified in 17/204 subjects(8.3%) treated with adalimumab. In patients not given concomitant methotrexate, the incidence was16/185 (8.6%), compared to 1/19 (5.3%) when adalimumab was used as add-on to methotrexate.
In patients with non-radiographic axial spondyloarthritis, anti-adalimumab antibodies were identified in8/152 subjects (5.3%) who were treated continuously with adalimumab.
In patients with Crohn’s disease, anti-adalimumab antibodies were identified in 7/269 subjects (2.6%) andin 19/487 subjects (3.9%) with ulcerative colitis.
In adult patients with psoriasis, anti-adalimumab antibodies were identified in 77/920 subjects (8.4%)treated with adalimumab monotherapy.
In adult plaque psoriasis patients on long term adalimumab monotherapy who participated in a withdrawaland retreatment study, the rate of antibodies to adalimumab after retreatment (11 of 482 subjects, 2.3%)was similar to the rate observed prior to withdrawal (11 of 590 subjects, 1.9%).
In patients with paediatric psoriasis, anti-adalimumab antibodies were identified in 5/38 subjects (13%)treated with 0.8 mg/kg adalimumab monotherapy.
In patients with moderate to severe hidradenitis suppurativa, anti-adalimumab antibodies were identifiedin 10/99 subjects (10.1%) treated with adalimumab.
In patients with moderately to severely active paediatric Crohn’s disease, the rate of anti-adalimumabantibody development in patients receiving adalimumab was 3.3%.
In adult patients with non-infectious uveitis, anti-adalimumab antibodies were identified in 4.8% (12/249)of patients treated with adalimumab.
In patients with moderately to severely active paediatric ulcerative colitis, the rate of anti-adalimumabantibody development in patients receiving adalimumab was 3%.
Because immunogenicity analyses are product-specific, comparison of antibody rates with those fromother products is not appropriate.
Paediatric populationJuvenile idiopathic arthritis (JIA)Polyarticular juvenile idiopathic arthritis (pJIA)The safety and efficacy of Humira was assessed in two studies (pJIA I and II) in children with activepolyarticular or polyarticular course juvenile idiopathic arthritis, who had a variety of JIA onset types(most frequently rheumatoid-factor negative or positive polyarthritis and extended oligoarthritis).
pJIA I
The safety and efficacy of Humira were assessed in a multicentre, randomised, double-blind,parallel − group study in 171 children (4-17 years old) with polyarticular JIA. In the open-label lead inphase (OL LI) patients were stratified into two groups, MTX (methotrexate)-treated or non-MTX-treated.
Patients who were in the non-MTX stratum were either naïve to or had been withdrawn from MTX atleast two weeks prior to study drug administration. Patients remained on stable doses of NSAIDs and orprednisone ( 0.2 mg /kg/day or 10 mg/day maximum). In the OL LI phase all patients received 24 mg/m2up to a maximum of 40 mg Humira every other week for 16 weeks. The distribution of patients by ageand minimum, median and maximum dose received during the OL LI phase is presented in Table 25.

Patients demonstrating a Paediatric ACR 30 response at Week 16 were eligible to be randomised into thedouble blind (DB) phase and received either Humira 24 mg/m2 up to a maximum of 40 mg, or placeboevery other week for an additional 32 weeks or until disease flare. Disease flare criteria were defined as aworsening of 30% from baseline in 3 of 6 Paediatric ACR core criteria, 2 active joints, andimprovement of 30% in no more than 1 of the 6 criteria. After 32 weeks or at disease flare, patientswere eligible to enrol into the open label extension phase.

Amongst those who responded at Week 16 (n=144), the Paediatric ACR 30/50/70/90 responses weremaintained for up to six years in the OLE phase in patients who received Humira throughout the study.
Over all 19 subjects, of which 11 of the baseline age group 4 to 12 and 8 of the baseline age group 13 to17 years were treated 6 years or longer.
Overall responses were generally better and, fewer patients developed antibodies when treated with thecombination of Humira and MTX compared to Humira alone. Taking these results into consideration,
Humira is recommended for use in combination with MTX and for use as monotherapy in patients forwhom MTX use is not appropriate (see section 4.2).
pJIA II
The safety and efficacy of Humira was assessed in an open-label, multicentre study in 32 children (2 -<4 years old or aged 4 and above weighing < 15 kg) with moderately to severely active polyarticular JIA.
The patients received 24 mg/m2 body surface area (BSA) of Humira up to a maximum of 20 mg everyother week as a single dose via SC injection for at least 24 weeks. During the study, most subjects usedconcomitant MTX, with fewer reporting use of corticosteroids or NSAIDs.
At Week 12 and Week 24, PedACR30 response was 93.5% and 90.0%, respectively, using the observeddata approach. The proportions of subjects with PedACR50/70/90 at Week 12 and Week 24 were90.3%/61.3%/38.7% and 83.3%/73.3%/36.7%, respectively. Amongst those who responded (Paediatric
ACR 30) at Week 24 (n=27 out of 30 patients), the Paediatric ACR 30 responses were maintained for upto 60 weeks in the OLE phase in patients who received Humira throughout this time period. Overall, 20subjects were treated for 60 weeks or longer.
Enthesitis-related arthritisThe safety and efficacy of Humira were assessed in a multicentre, randomised, double-blind study in 46paediatric patients (6 to 17 years old) with moderate enthesitis-related arthritis. Patients were randomisedto receive either 24 mg/m2 body surface area (BSA) of Humira up to a maximum of 40 mg, or placeboevery other week for 12 weeks. The double-blind period is followed by an open-label (OL) period duringwhich patients received 24 mg/m2 BSA of Humira up to a maximum of 40 mg every other weeksubcutaneously for up to an additional 192 weeks. The primary endpoint was the percent change from
Baseline to Week 12 in the number of active joints with arthritis (swelling not due to deformity or jointswith loss of motion plus pain and/or tenderness), which was achieved with mean percent decrease of -62.6% (median percent change -88.9%) in patients in the Humira group compared to -11.6% (medianpercent change -50.0%) in patients in the placebo group. Improvement in number of active joints witharthritis was maintained during the OL period through Week 156 for the 26 of 31 (84%) patients in the
Humira group who remained in the study. Although not statistically significant, the majority of patientsdemonstrated clinical improvement in secondary endpoints such as number of sites of enthesitis, tenderjoint count (TJC), swollen joint count (SJC), Paediatric ACR 50 response, and Paediatric ACR 70response.
Paediatric plaque psoriasisThe efficacy of Humira was assessed in a randomised, double-blind, controlled study of 114 paediatricpatients from 4 years of age with severe chronic plaque psoriasis (as defined by a PGA ≥ 4 or > 20% BSAinvolvement or > 10% BSA involvement with very thick lesions or PASI ≥ 20 or ≥ 10 with clinicallyrelevant facial, genital, or hand/ foot involvement) who were inadequately controlled with topical therapyand heliotherapy or phototherapy.
Patients received Humira 0.8 mg/kg eow (up to 40 mg), 0.4 mg/kg eow (up to 20 mg), or methotrexate 0.1- 0.4 mg/kg weekly (up to 25 mg). At Week 16, more patients randomised to Humira 0.8 mg/kg hadpositive efficacy responses (e.g., PASI 75) than those randomised to 0.4 mg/kg eow or MTX.

Patients who achieved PASI 75 and PGA clear or minimal were withdrawn from treatment for up to36 weeks and monitored for loss of disease control (i.e. a worsening of PGA by at least 2 grades). Patientswere then re-treated with adalimumab 0.8 mg/kg eow for an additional 16 weeks and response ratesobserved during retreatment were similar to the previous double-blind period: PASI 75 response of 78.9%(15 of 19 subjects) and PGA clear or minimal of 52.6% (10 of 19 subjects).
In the open label period of the study, PASI 75 and PGA clear or minimal responses were maintained forup to an additional 52 weeks with no new safety findings.
Adolescent hidradenitis suppurativa
There are no clinical trials with Humira in adolescent patients with HS. Efficacy of adalimumab for thetreatment of adolescent patients with HS is predicted based on the demonstrated efficacy and exposure-response relationship in adult HS patients and the likelihood that the disease course, pathophysiology, anddrug effects are substantially similar to that of adults at the same exposure levels. Safety of therecommended adalimumab dose in the adolescent HS population is based on cross-indication safetyprofile of adalimumab in both adults and paediatric patients at similar or more frequent doses (see section5.2).
Paediatric Crohn’s diseaseHumira was assessed in a multicentre, randomised, double-blind clinical trial designed to evaluate theefficacy and safety of induction and maintenance treatment with doses dependent on body weight(< 40 kg or ≥ 40 kg) in 192 paediatric subjects between the ages of 6 and 17 (inclusive) years, withmoderate to severe Crohn´s disease (CD) defined as Paediatric Crohn's Disease Activity Index (PCDAI)score > 30. Subjects had to have failed conventional therapy (including a corticosteroid and/or animmunomodulator) for CD. Subjects may also have previously lost response or been intolerant toinfliximab.
All subjects received open-label induction therapy at a dose based on their Baseline body weight: 160 mgat Week 0 and 80 mg at Week 2 for subjects ≥ 40 kg, and 80 mg and 40 mg, respectively, for subjects< 40 kg.
At Week 4, subjects were randomised 1:1 based on their body weight at the time to either the Low Dose or
Standard Dose maintenance regimens as shown in Table 28.

Statistically significant increases (improvement) from Baseline to Week 26 and 52 in Body Mass Indexand height velocity were observed for both treatment groups.
Statistically and clinically significant improvements from Baseline were also observed in both treatmentgroups for quality of life parameters (including IMPACT III).
One hundred patients (n=100) from the Paediatric CD Study continued in an open-label long-termextension study. After 5 years of adalimumab therapy, 74.0% (37/50) of the 50 patients remaining in thestudy continued to be in clinical remission, and 92.0% (46/50) of patients continued to be in clinicalresponse per PCDAI.
Paediatric ulcerative colitisThe safety and efficacy of Humira was assessed in a multicenter, randomized, double-blind, trial in 93paediatric patients from 5 to 17 years of age with moderate to severe ulcerative colitis (Mayo score 6 to 12with endoscopy subscore of 2 to 3 points, confirmed by centrally read endoscopy) who had an inadequateresponse or intolerance to conventional therapy. Approximately 16% of patients in the study had failedprior anti-TNF treatment. Patients who received corticosteroids at enrollment were allowed to taper theircorticosteroid therapy after Week 4.
In the induction period of the study, 77 patients were randomized 3:2 to receive double-blind treatmentwith Humira at an induction dose of 2.4 mg/kg (maximum of 160 mg) at Week 0 and Week 1, and 1.2mg/kg (maximum of 80 mg) at Week 2; or an induction dose of 2.4 mg/kg (maximum of 160 mg) at Week0, placebo at Week 1, and 1.2 mg/kg (maximum of 80 mg) at Week 2. Both groups received 0.6 mg/kg(maximum of 40 mg) at Week 4 and Week 6. Following an amendment to the study design, the remaining16 patients who enrolled in the induction period received open-label treatment with Humira at theinduction dose of 2.4 mg/kg (maximum of 160 mg) at Week 0 and Week 1, and 1.2 mg/kg (maximum of80 mg) at Week 2.
At Week 8, 62 patients who demonstrated clinical response per Partial Mayo Score (PMS; defined as adecrease in PMS ≥ 2 points and ≥ 30% from Baseline) were randomized equally to receive double-blindmaintenance treatment with Humira at a dose of 0.6 mg/kg (maximum of 40 mg) every week (ew), or amaintenance dose of 0.6 mg/kg (maximum of 40 mg) every other week (eow). Prior to an amendment tothe study design, 12 additional patients who demonstrated clinical response per PMS were randomized toreceive placebo but were not included in the confirmatory analysis of efficacy.
Disease flare was defined as an increase in PMS of at least 3 points (for patients with PMS of 0 to 2 at
Week 8), at least 2 points (for patients with PMS of 3 to 4 at Week 8), or at least 1 point (for patients with
PMS of 5 to 6 at Week 8).
Patients who met criteria for disease flare at or after Week 12 were randomized to receive a re-inductiondose of 2.4 mg/kg (maximum of 160 mg) or a dose of 0.6 mg/kg (maximum of 40 mg) and continued toreceive their respective maintenance dose regimen afterwards.
Efficacy Results
The co-primary endpoints of the study were clinical remission per PMS (defined as PMS ≤ 2 and noindividual subscore > 1) at Week 8, and clinical remission per FMS (Full Mayo Score) (defined as a Mayo
Score ≤ 2 and no individual subscore > 1) at Week 52 in patients who achieved clinical response per PMSat Week 8.

Quality of lifeClinically meaningful improvements from Baseline were observed in IMPACT III and the caregiver Work
Productivity and Activity Impairment (WPAI) scores for the groups treated with Humira.
Clinically meaningful increases (improvement) from Baseline in height velocity were observed for thegroups treated with adalimumab, and clinically meaningful increases (improvement) from Baseline in
Body Mass Index were observed for subjects on the high maintenance dose of maximum 40 mg (0.6mg/kg) ew.
Paediatric UveitisThe safety and efficacy of Humira was assessed in a randomized, double-masked, controlled study of 90paediatric patients from 2 to < 18 years of age with active JIA-associated noninfectious anterior uveitiswho were refractory to at least 12 weeks of methotrexate treatment. Patients received either placebo or20 mg adalimumab (if < 30 kg) or 40 mg adalimumab (if ≥ 30 kg) every other week in combination withtheir baseline dose of methotrexate.
The primary endpoint was ‘time to treatment failure’. The criteria determining treatment failure wereworsening or sustained non-improvement in ocular inflammation, partial improvement with developmentof sustained ocular co-morbidities or worsening of ocular co-morbidities, non-permitted use ofconcomitant medications, and suspension of treatment for an extended period of time.
Clinical Response
Adalimumab significantly delayed the time to treatment failure, as compared to placebo (See Figure 3,
P < 0.0001 from log rank test).The median time to treatment failure was 24.1 weeks for subjects treatedwith placebo, whereas the median time to treatment failure was not estimable for subjects treated withadalimumab because less than one-half of these subjects experienced treatment failure. Adalimumabsignificantly decreased the risk of treatment failure by 75% relative to placebo, as shown by the hazardratio (HR = 0.25 [95% CI: 0.12, 0.49]).
